J CONE-TUBE.

Specification of Letters Patent.

Application filed March 25,1915. Serial No. 17,038.

To all whom it may concern:

Be it knownthat I, HENRY L. T\IFFANY, a citizen of the United States, and aresident of South Dartmouth, in the county of Bristol and State of Massachusetts, have ined to receive or have wound thereon yarn,

thread or the like of the commonly known cone winding form and from which the yarn is drawn ofi axially. or substantially so.

In certain aspects thereof, my invention is an improvement upon that shown in the patent toCharles Gess, No. 986,379, dated March 7, 1911.

In order that the principle of the invention may be readily understood, I have disclosed a single embodiment thereof in the accompanying drawing, wherein- Figure 1 is a side elevation of a cone tube embodying my invention; Fig. 2 is a vertical, central section. thereof; Fig. 3 is a plan view of the tube shown in Fig. 1; Fig. 4 is a cross sectional view thereof; Fig. 5 is a. sectional view of the tip end of the tube; Fig. 6 is a plan view of the blank from which the cone tube is wound; Fig. 7 is a side elevation of the upper portion of a cone tube constituting a modified form of my invention; and Fig. 8 is a vertical, central section taken. through the cone tube shown in Fig. 7.

Cone tubes adapted to receive or have yarn or thread wound thereon and from which said yarn or thread is drawn ofl axially when in upright position are customarily formed of paper rolled in one or more layers or coils into conical form. These tubes are adapted to be mounted for winding upon tapering arbors of the general shape of the tubes and extending through said tube to within an inch or two of the tip end thereof. The ends of these conical tubes generally protrude somewhat from the complete yarn or thread mass. A cone tube of this general character but having an inturned apex end is disclosed in said Gess Patent No. 986,379,.

and I have represented the disclosed embodiment of my invention as applied thereto.

Referring more particularly to the drawingsand to'the single embodiment of the invention here illustrated, the blank from WhlCh the cone or tube is formed is represented at 1 in Fig. ,6, it beingv preferably of the segmental shape there shown. The said blank is coiled as indicated in Fig. 4 into a suitable number of contacting layers and the inner edges of the said layers should for the best results terminate substantially flush with each other, as indicated at 2 in Fig. 5.

Owing to the fact that the conical tubes are markedly tapering to facilitate the unwinding of the yarn or thread (suchtapering materially exceeding that of the usual spinning spindle), it is exceedingly important in effecting the best results that such cone tubes be superficially roughened, thus preventing the slipping or displacement of the yarn or thread as the first series of layers thereof are wound upon the tube and subsequently. This tendency to displacement, particularly exists to a marked degree in a cone having Patented Mar. 14, 1916.

of the first laid layers,

a decided taper,-but it is nevertheless of importance that the cone tube and the yarn package wound thereon be of decided or markedly tapering form. Such roughening may be of any suitable character, thoughpreferably it is effected by providing the cone tube with longitudinal ridges 3 inclined from top to bottom, such roughening being efi'ecte'd either prior or subsequently to the coiling of the paper or other material into tube form, but preferably While the material is in its flat form. If as prepared the cone tube be superficially roughened, the roughened portion is removed from the tip portion of the tube which, as stated, should present no obstruction to the unwinding of the yarn or thread and especially to the unwinding of the first laid layers thereof.

In order to prevent the first laid coils or layers of the yarn or thread from-contacting with the tip end of the cone tube as they are unwound therefrom, the tip end 5 thereof is inturned or upset in any suitable manner, as represented most clearly in Figs. 1, 2 and 5. The tip end of the cone tube should, for effooting the best results, be very materially inturned and if not wholly, to close said tip end, and the inturned end may be turned into the cone tube to any desired extent so as to provide a downwardly extending edge portion.

preferably so as substantially,

The tip end of the cone tube, as yarn orthread is being wound thereon, projects very materially beyond the tapered end of the supporting arbor. The approximate position of the outer end of the arbor is indicated by the dotted line .1.'.v in Fig. 2, and is therefore free from contact with the said tip end of the cone tube. It is thereforepossible to upset or inturn the tip end of the cone to a very marked degree and so as effectively to prevent the breaking or chafing of the yarn or thread by said tip end as the yarn or thread is unwound.

The cone is markedly conical in order to permit the yarn to free itself from the roughened surface when drawn from the end of the cone andis provided with stiff, cone supporting, side walls to sustain the usually large and heavy package. The tip end of the cone preferably is not only inturned but is smooth, the roughened surface of the body of the cone blending into the smooth,

inturned surface of the tip. The said inturned tip end is preferably indifierently centered internally with respect to the axis of the cone, this being possible because the .tip end of the cone extends beyond the driver. This is a matter of practical importance, inasmuch as if, in manufacturing the cone, the apex end thereof be somewhat warped or distorted, the fact that the tip end extends beyond the driver permits it to conform in position substantially to the driver, whereby the yarn or thread as drawn oil will not be obstructed or impaired by said warped or deflected portion.

In effecting the inturning of the tip end of the cone tube, the material of such tip may be somewhat twisted or circumferentially displaced, as indicated at 6 in Figs. 1 and 3.

When the cone tube is in its normal condition,that is, before the tip end thereof has been inturned,such tip end is substantially unyielding to inward pressure. When, however, the material of the tube has been circumferentially displaced, then the arch effect existing prior to inturning is materially lost and the twisted portions of the edge, because of their displacement, will more readily yield inwardly. This inturning may be satisfactorily effected by subjecting the unturned end to the action of a die, the die and cone tube having a movement of relative rotation. Such relative rotation of the cone tube and die coincidently softens the material of the tip end portion, thus enabling it to be turned inwardly and to lie snugly in the die and to'receive the smooth, highly desirable, polished surface. Such softening of the ti end renders such tip end less stiff and lacking in rigidity than the body of the tube, it being therefore more pliable and yielding than the bod thereof. This, however, renders the tip en liable to be crushed or damaged in transportation. In order to overcome the effect of such s0ftening action and to reinforce the tip end of the tube, and in certain cases so as merely or substantially to neutralize the softening due to the inturning action, Iiprovide a reinforcing element or device which in the preferred embodiment of the invention is represented in Figs. 2 and 5 as a cap 7 of: thin sheet steel, which is adapted to be in serted within the tip portion of thetube of the cone may be rolled thereabout. Preferably the cap is provided at its lower edge with a series of teeth or projections 8 which may be slightly out-turned so as readilyto penetrate into the inner wall of the cone tube as represented in Figs. 2 and 5. After the insertion of the cap 7, if it be so applied, the end of the cone tube is upset or inturned' in any suitable manner, as by subjectingit to the action of a die, which has a movement of relative rotation with respect to the cone tube.

While I preferably provide a unitary cap p ece, I may reinforce the tip end by-a series of more or less distinct parts which converge from their lower ends to the central portion of the inturned tip end.

Within the-scope of my invention, the reinforcing member or cap piece may be apphed to the outer surface of the cone tube. Such form of my invention is illustrated in Figs. 7 and 8, wherein is shown a cap'piece 9 having at its lower edge teeth 10 adapted to penetrate theouter surface of the cone.

tube. Such cap piece is preferably applied subse uent to the inturnin thong within the scope o my invention, it

may be applied at any suitable time, as,-

for example, simultaneously or substantially simultaneously with the inturning action. In order .to. prevent chafing or breaking of the yarn or thread in the unwmdmg action, the outer wall of the body of the tip; end,

of the cone tube should merge without 1 in. terruption and smoothly into the lower edge a of the cap 9. Preferably alsothe outer surso that it presents no obstruction to the unwinding of the yarn or thread. The capiece shown in both forms of the invention is preferably provided with an axial. open- I face at least of the cap 9 is highly polished ing 11 coinciding with the axial opening which may be left in the tip end of the cone tube.

A cone tube constructed in accordance with my invention may readily be transported without liability of damage to the tip end, even though such cone tubes have heavy packages of yarn wound thereon and from which said tip ends protrude.

Having thus described one illustrative embodiment of my invention, I desire it to be understood that although specific terms are employed, they are used in a generic and descriptive sense and not for purposes of limitation, the scope of the invention being set forth in the following claims.
